Most new grads at Facebook or Airbnb make it to E4 typically after 1 year without any problems. Is this equivalent to a “senior software engineer” at other equivalently selective places (only considering top companies)? It would seem like it’s pretty easy to be a senior engineer at Facebook and Airbnb after 1 year then, so these are good places for career acceleration?
E5 is easy. A matter of 2-5 years depending on performance. E6 is much harder - it’s more like a tenure at that time
E3 is Jr soft eng, e4 is soft eng, e5 is mid/sr and e6 is sr
E5 is considered senior at FB
How hard is the promotion from E4 to E5?
